ResumoSweat was collected from the arms of 24 normal healthy subjects while they sat in a hot chamber. Blood, urine and saliva samples were also collected. These were analyzed for lead by atomic absorption spectrophotometry. Sweat lead levels recorded in this study are lower than those previously reported. Subjects with mean blood lead levels of 8.62 μg dl (range 6–13.6) had mean sweat levels of 5.2 μgl−1 (range 1.5–13.0). ≈25% of thier urinary levels. Although salivary lead levels with a mean of 4.8 μgl−1 (range 2.5–10) are comparable to sweat levels, their relationship to blood lead levels is poor (r = −0.186 compared with r values of 0.7208 and 0.234 for sweat and urinary levels, respectively).
